Come Out Fighting

A group of delinquents on their way to summer camp get stuck in a haunted house.

The gang is sent to the Wilton Reform School after they are unjustly convicted of stealing a truck. Bill Collins, brother of co-leader Danny, becomes involved in a killing and, while also innocent, is convicted and sentenced to death. Through a series of events, Muggs, Glimpy, Danny and the rest of the gang, learn that Knobby, a henchman of Luke Manning, knows something about the murder.

Muggs is tricked into entering a Civilian Conservation Corps camp by Danny in order to get in shape. Muggs resists and battles with the camp captain and with other campers. He also becomes involved in trying to help one of his friends get out of trouble.

The East Side Kids discover that one of their own, Danny, is torn between staying in school and becoming a boxer, and is getting mixed up with gangsters.

The East Side Kids try to fix up a house for newlyweds, but find the place next door "haunted" by mysterious men.

A group of young men who work at an aviation factory begin to suspect that a doctor who runs an air ambulance service is secretly a spy transporting secret information from the plant to enemy agents.

A street kid has dreams of becoming a jockey. He gets his chance when he and his gang discover a poor old man who has a championship race horse. The man agrees to let the boy ride his horse in a race, but first the gang must get enough money to pay for the race's entry fees.

Danny helps to capture a wanted criminal and receives a $200 reward. However, he has a falling out with the gang when they believe he should share the money with them. Complications ensue when the crook that Danny helped capture escapes from jail and comes looking for him.

Muggs and Glimpy, two East Side Kids in the army, return to their neighborhood, supposedly on furlough; actually, Muggs has been honorably discharged with a physical defect, but he tells no one of this. Danny, another East Side kid, is in jail because a large amount of medical supplies have been stolen from the warehouse where he works. Muggs see Spider, a new member of the gang, flashing a large amount of money around, and Muggs shrewdly turns toughie, boasting that he has a dishonorable discharge because of thievery. This leads Spider to confide in Muggs that he is the one who has been aiding in the theft of supplies from the warehouse, and he gets paid for the loot by Larry, operator of a nightclub where Muggs' sister, Milly, is an entertainer. Fingers, a henchman for Larry, kills Spider when he learns that Muggs has been let in on the operation. The police then suspect Muggs of killing Spider.

Ordered by a judge to get a job, Muggs McGinnis is hired by wealthy Mrs. Murray, who has a penchant for picking up trouble-prone servants. At an engagement party for Mrs. Murray's spoiled daughter Brenda, Muggs enlists his pals as extra help.

The gang is friend with a millionaire because they saved him from an agression. However, the gang is suspecting that the man's son was actually one of the agressors.
